HYDRAULIC SAUSAGE-STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,826, dated March 11, 1884;

(,o model.)

T0 @ZZ whom, t may concern.-

Beit known that I, FREDERICK W. TUERK, J r., a citizen of the United States, residing at Chicago, in the county of' Cook and State of Illinois, have invented certain new and useful Improvements in Hydraulic Sausage-Stuffing Machines; and Ihereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of devices used in the manufacture of sausages lfor stuffing the `intestine with prepared sausage-meat.

It is the object of my invention to provide a machine wherein two chambers shall be formed, the upper and larger to contain sausage-meat and a piston-head, and the lower and smaller a pist-on to be operated by hydraulic pressure, the construction being such thatV the water will serve as a lubricator for the piston, but will be prevented, without the use of packing, from entering the upper chamber containing the sausage-meat, and being such also that the difference in the dimensions of the two chambers, and consequently the size of the piston, may be gaged according to the pressure obtainable from the water-supply at the place where the device is to be used,

the piston and cylinder inelosing the piston being made relatively small for a high pressure and relatively large for a low pressure, whereby uniform results may be obtained without waste of water, thus permitting the economizing of water in proportion to the pressure.

To this end my invention consists in providing a hollow cylinder or shell, preferably formed of metal, and having its lower portion narrower than its upper, and a second cylinder of dimensions smaller than theiirst-named, to be contained within the narrower portion of the same, and having a piston-head of dimensions to fit within the upper portion of the first-named cylinder, to serve as a piston, and combining with these features means. for admitting water under pressure into the cylinder below the piston, and discharging it therefrom at will, and also a tube at the top of the device to form an outlet forl the sausage-meat.

My invention consists, further, in certain details of construction and combinations of parts, all as hereinafter more fully set forth.

Referring to the drawings, Figure 1 is a central vertical section of my device, taken on the line l I of Figs. 2, 3, and 1l, and viewed in the direction ofthe arrow-heads; Fig. 2, a front elevation of the same; Fig. 3, ahorizontal section taken on the irregular lines 3 3 of Figs. l and 2, showing the interior construction of the device; and Fig. et, a plan view of my device with the top in position.

A is the shell, which in use is always vertical, preferablyv of metal, and cast, for the-sake of convenience, in two parts, althoughit may be cast as a whole. In either ease an internally-convex bottom is provided, as shown in Fig. l of the drawings. IVheifiormedin the first-named manner, lateral fianges are caused to project, the one i/ from the lower edge of the upper portion, andthe one y from the upper edge of the lower portion, as shown in the drawings, and the two parts are firmly secured together by means of bolts passing through bolt-holes provided in the said flanges and nuts. Vhen the shell A is formed as a whole, only the iiauge 1/ exists, which in this ease may be shorter than in the other, since it then only serves as a shoulder.

B-is a hollow cylinder, cast separately from the outer shell, just described, and provided with a lateral flange, z, extending down from its upper edge to a depth sufficient to afford a thickness capable of offering the required'resistance, and to insure smoothness and evenness of its motion within the said shell, and of the requisite length to fit closely within the same. The'cylinder B forms a piston, and is cast hollow, in preference to solid, to save material and reduce its weight to the minimum. Both ends are closed, the lower in the casting, and the closing of the upper being effected by nieansof a tightly-fitting cover, b', having a lateral flange, c, around its upper edge, whereby it is permitted. to rest upon the projecting flange fu', formed at a suitable distance below the edge of the said opening around the inner wall of the cylinder B. The body of the cover b extends downward the width of the iiange fv. A suitable handle, a, is provided upon the cover, to afford a means for lifting the piston B whenever it shall be necessary to remove the latter. To save :niaterial and the labor of boring out the whole IOO depth of the shell A, and at the same time to provide sufiicient sliding-surface to insure a sniooth motion of the piston B, the core used in casting is formed to shape the interior of the lower portion of the shell in a manner to bring but a small portion of the external surface of the piston into close contact with the shell, as shown at t, whereby the employment of packing is obviated, the friction lessened, and a space is provided between the cylinder and shell where water may enter to afford the necessary lubrication. The piston B may be nickel-plated on its exterior surface, to prevent its rusting by contact with the water; or it maybe formed entirely of brass, for the saine purpose, or, if desired, the projection shown at t may, to prevent rusting, consist of a brass ring cast into the iron shell. rlhe cylinder is i made somewhat longer than the height of the lower and narrower portion of the shell, not only to permit the i'laiige or pistoii-liead to lie within the upper portion, but also to provide aJ receptacle for water, which may be forced into the same by the action of the piston B, whence it escapes through an outlet, s, providcdin the flange y', and having a hose or pipe connection, s.

C is a` tliree-way valve, connected with the handle r by means ot' a rod, c', which projects through a suitable hole made through the ilaiiges of the shell A, where the handle Ir is secured toit. lhe tliree-way valve fits within a pipe, q, formed to receive it, and the pipe q in turn is inserted into a tube, q', which projects from the side of the shell A, near the lower end of the same, and leads into its interior. rlhe pipe l is open at its outward extremity, where one end of a hose or pipe, p, is attached, the other end being connected with a hydrant or reservoir whence the hydraulie power is obtained. At one side of the pipe (j is an opening` provided with suitable means for attaching the hose or pipe p', through which the waste water escapes. lhe three-way valve C is formed after the ordinary manner ot' tlirce-way cocks-viz., of a plug having a transverse channel through its center, and an auxiliary channel formed in one side of the plug equidistant from the openings ot' the transverse channel, to meet the latter.

.D is the cover, hinged to one side of the shell, as shown at o. The portion ofthe hinge which projects from the cover has an extension, o, which strikes against the side of the shell when the cover is raised, to prevent tipping back ot' the latter farther than is necessary completely to uncover the opening to the interior of the device. The cover Dis provided with an outlet-tube, E, bent to forni an elbow, which is made tapering toward its mouth, over which a spout, c', having a iiange, m, around its larger end, is fitted and firmly secured in place by means of a collar, c, provided on opposite sides with inclined or spiral slots n, to receive the pins 71, formed externally and opposite to each other, one on cach side near the mouth of the outlet-tube. To secure the spout c firmly upon the tapering end of the outlet, it is first adjusted thereto, when the collar c is slipped over it, to bring the pins 71 within the slots n, and as the collar is turned and forced backward it becomes more and more firmly secured in position, while its pressure against the ilange m on the spout c/ n' rml y holds the latter in place. This construetion permits spouts with nozzles of different sizes to be readily substituted.

F l1 are bearings formed on the exterior siii'- face of the shell A, to receive the bolts 7, which support the swinging eyebolts 7.. These eyebolts lit into recesses 7.", formed in the lips Lt', which project from the cover and beyond the wall of the shell A over the ilange j//. Vhen the cover is down, the mits i are screwed upon the bolts 7.: firmly, to secure it in place. Vhen it. is desired to raise the cover, a few turns of the nuts `i will loosen them sufficient to permit the bolts 7.' to be swung back on their hinges out ofthe recesses, and thus free the cover.

To operate my device, conveniently supported by the lower flange, y', which may be made to rest upon a table provided with an opening in its top to admit the lower portion ofthe shell, the cover is raised, when the upper chamber, formed in the shell by the position ofthe j iiston-head, is iilled with sausagemeat. The cover is then fastened down by means of the nuts i and bolts 7:, when the intestine, oi' whatever the covering may be, is slipped over the mouth of the spout c'. All being now in readiness, the operation of stuffing the casing begins. lhe hose )i is connected with the water-supply, and the threeway cock turned by means of the handle r, to admit water into the spaces between the convex bottoni of the shell A. and the piston. The pressure exerted by t-lie water drives the piston upward, thereby forcing the meat through the outlet E and spout c/ into the casing. Vhen the charge ot' meat shall have been exhausted, or when, for any other reason, it shall be desired to lower the piston, the supply of water is eut off, and the three-way cock turned to cause the auxiliary channel to register with,

the projection q', whereby one end ot' the main channel will be closed by its position against the wall ofthe tube (I, while the opposite end registers with the opening to which the hose or pipe p is secured, thus providing a passage for the waste water to the hose p', which leads it ofi, and at the same time liastens the evacuation of the water by the suction produced, and causes the piston to fall by gravity.

lt' desired, a dial may be placed under the end of the handler, as shown at x in Fig. Il of the drawings, to indicate the angle to which it is necessary to turn thchandle for either of the before-mentioned purposes, or for the regulation ot' the pressure to any desired degree below its full capacity.

Among the advantages attendant upon the use of my device over others for 'a like purpose are that it operates both ways by the simple turning of a valve, and that it is capable of being supplied with meat while the piston is descending, whereby loss of time is avoided. rIhe piston will descend by its own gravity alone in a short time while the water is discharging, and the time consumed in the descent of the piston may be considerably lesscned if the discharge-hose p be made long enough in a vertical direction to create material suction by the fall of the water. By making the'discharge-hose of considerable length, the waste water in the shell is drawn off very rapidly, and the piston descends with proportionate rapidity.

In my device, as will be seen, power is ap- 'plied only in one direction-to wit, .to propel the piston upward to effect the stuiiing. The return is effected, as just described, wholly through the medium of gravity acting upon the piston itself and upon the watergwhence only half the power is expended in my machine that is expended in other machines for the same purpose, rendering it very economirIhis is of course incident to the vertical position of the cylinder. If the cylinder were placed in a horizontal position, power would have to be applied to cause thenegative as well as the positive motion. i

What I claim'as new, and desire to secure by Letters Patent, is-

l. A sausage-stuffing machine comprising,

in combination, a hollow cylinder or shell made narrowest toward its lower end, a second cylinder of dimensions smaller than the iirst named, to t within thev narrower portion of the latter, and provided with a piston-head of dimensions to fit within the upper portion of the outer cylinder to serve as a piston, means for admitting water under pressure into the cylinder below the pistou and discharging it therefrom at will, and a tube at the top of the device to form an outletA for the sausage-meat,

substantially as described. 2. In a stuffing-machine, the combination of the shell A, having an outlet, s, hollow cylinl under pressure into its lower end, and for discharging the same, and provided also with an outlet-tube at its upper end for the discharge of the sausage-meat, and with a shoulder, y', having an opening, s, in combination with the piston comprising the cylinder B within the lower portion of the shell and iange z, tting within the upper portion, the said cylindrical part B being somewhat higher than the interior of the narrower portion of the shell within which it iits, whereby when it rests upon the bottom of the same a space intervenes between the shoulder y and the piston-head, substantially as described, and for the purpose set forth.

4. In a stuffing-machine, the combination of the following elements, .vizz the shell A, provided with an outlet, s, and having itsupper and lower portions of unequal size, as shown, and provided with an internally-convex bottom, piston B, provided'with alateral flange, z, fitting within the upper portion of the shell A, and with the cover b and handle a, three-way valve C, operating within the tube q, which is connected with a water-supply, and provided with an outlet-pipe, p', cover D, hinged to one side of the said shell and detachably secured thereon by means of swinging eyebolts having their bearings upon the shell A, and provided with an outlet-tube, E, bent to form an elbow and made tapering toward its mouth, and spout e, secured thereon by means of a collar, e, all being arranged to operate substantially as described.
